Abstract:
Relative projection constants of certain classes of cubspaces of codimension 2 in
$l_\infty^{2n}$
are found. The minimal projections under considerations are of two kinds, with unit norm and with norm larger than 1.
Keywords:
projection operator, space, subspace, relative projection constant.
